To all whom it may concern:

Be it known that I, LUDWIG VON Siissresiding in St.

Georgen, near St. Gallen, in the canton of St.

Gallon, Republic of vented certain new and useful Improvements in Amparatus for Drying Macaroni and other Substances; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper -tains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form' a part of this specification.

. This invention relates to drying apparatus in whichthe draftv is caused in a drying chamber, by the reciprocation of two pistons arranged at different sides of the material to be dried. 'As such apparatus are mostly constructed of wood it is obvious that the frictional surfaces are subjected to rapid wear and tear and leakages or lossesof pres 'sure frequently occur. The continual shrinking and swcllingof the wood under the infiuence of the moist air causes loss of pressure and also jamming of the'pistons and consequently a great expenditure of energy.

The above mentioned disadvantages are overcome according to the present invention by positively connecting the two pistons in the drying apparatus by means of rods and supporting them on carrying-rollers by means of some of such rods.

The accompanying drawings illustrate one form of the invention.

Figure 1 is a sectional elevation, Fig. 2 a horizontal section on the line AB Fig. l and Fig. 3 a section on the line 'C'D of Fig. 2. I

c indicates in the drawing the box or casiln. which is dividedinto two drying chambcrs by a double partition a 6 is the frame for receiving the goods and c d are the pistons arranged at either side of the frame, which pistons are positively connected with each other by means 'of rodsc, 2 Both pistons rest at the bottom on slide rollers m by means of the rods, c while they are guided. at the top against similar rollers, nby'rneans of rods, c The slide rollers m, as well as the rollers, 12 are arranged in pairs on transverse shafts which are carried by suitable l'icarings on the box or casing r, by

Switzerland, have inrod f, guided in nine, f in the front wall of the casing to the end of the longer arm of a lever, h, having arms of unequal len h. j

ranged in the side wal s of the box. IEecen .trics g are mounted on shafts,-p, to permit these doors to be kept in the closed position or to bring them into the same. The shafts, p, are carried by supports, 1 fastened to the casing and may be rotated by a lever s, mounted on the shafts.

the renewal o the air in t e box an between the pistons after the opening of these flaps.

v are receptacles for the water in order to continually keep the humidity ofthe air at a certain degree.

When the crank shaft is rotating the pistons which are in the same chamber are 'simultaneonsly moved to and fro. Witheach is driven through the goods arran ed on the frame while the air displaced by t e one pieton on its'outer side is conducted to the rear of the other piston through the passage, Z, so

and the spaces outside. I v 1 As already mentioned the weight of the therefore the usual considerable wear and the piston itself is avoided. Further the power required for displacing the piston is much less than if the pistons directly slide on the bottom of the chamber. i

What I claim is: 1. In drying apparatus comprising a casing means within the casing for receiving the material to be dried,'a piston on each side of said means, and mechanism for reciprocating said pistons, the combination of rods positively connecting the pistons and rollers in contact with said rods for the purposes hereinbefore set forth.

2. In drying apparatus comprising a casing means within the casing for receiving the material to be dried and a piston on each side of said means, rods for positively connecting said pistons, rollers engaging with said r'ods, a rocking lever having one arm longer than the other, means for connecting one piston to the end of the longer arm, and means for rocking said lever, said means hemg connected to the end of the shorter arm,

substantially as and for the purpose set forth.-

3. In a drying apparatus, the combination with a casing inclosing a frame for receiving the material to be dried, a piston on each side of said means, means connecting the pistons, mechanism for operating the pistons, and a partition in the casing to provide a passage to connect the spaces outside the heads of the pistons.

4. In a drying apparatus, the combination with a casing formed with a piston receiving space connected near its ends by a passage, a drying frame in the space, a piston operating in the space on one side the drying frame, a second piston in said space and on the opposite side/of said drying frame, means connecting the two pistons, andnieans operating the pistons, the air in the space adjacontone piston beingforced by said piston through the passage into the space opposite the other piston.

svaise 5. In a drying apparatus; the combination.

with a casing having a frame to receive the material to be dried, a piston on each side the .casing to force air through the frame as said pistons are operated, means connecting the pistons, means for operating the pistons, and

means for supplying thespace between the 7. In a rying apparatus, the combination with a casing, a partition dividing the casing into two compartments formed with passages, a material receiving frame in each compartment, a pair of pistons iii each compartment, each said frame being between the respective pair of pistons, rods connecting the pair of pistons in each compartment, the air adjacent a )iston being displaced and. forced through the passage adjacent its complemen'tal piston, means for supplying the air to the compartments, a pair of pivoted levers disposed at an angle to each other, links connecting the pairs of pistons and the levers, a shaft having two cranks disposal.

out of ali'uement with each other, ant rods connecting the levers and the cranks, whereb 7 upon movement of the shaft the two sets of pistons will for a period be moving in op posite directions.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
